| 21. | The figure below displays commercial examples of thermionic emitters and electron guns produced at Heatwave Labs Inc.
|
| 22. | Valve electrometers use a specialized vacuum tube ( thermionic valve ) with a very high plate ) circuit.
|
| 23. | Thermionic emission can be used to measure the work function of both the hot emitter and cold collector.
|
| 24. | Example of an electron emitting a ) Thermionic Emitter and an electron accelerating b ) Electron Gun Assembly.
|
| 25. | This " shadow " led to discovery of Thermionic emission, the basis for Vacuum tubes and electronics.
|
| 26. | It was also called a thermionic valve, vacuum diode, kenotron, thermionic tube, or Fleming valve.
|
| 27. | It was also called a thermionic valve, vacuum diode, kenotron, thermionic tube, or Fleming valve.
|
| 28. | Cold cathode lamps are generally less efficient than thermionic emission lamps because the cathode fall voltage is much higher.
|
| 29. | The thermionic cameras were made from brass, using round daguerreotype plates which exposed a diameter of 8 cm.
|
| 30. | Plasma is produced via discharge from a barium-oxide coated cathode, which emits electrons via thermionic emission.
